I have a Texas Instruments TI-nspire CX calculator for sale. Only owned this for a few months and used it literally once, so it's basically new. Bought new at Wal-Mart for $140. It comes with charging cable and a sync cable to connect to other TI calculators. The screen is a color screen, and has the ability to do more things than I am willing to learn. Basically, this thing is a computer in calculator form! Asking $120. Message me on here if interested. Thanks!
